Title:

MAGNETIC SEPARATOR FOR IMPROVING GRADE OF REFINED ORE AND REDUCING SLAGS

Document Type and Number:

WIPO Patent Application WO/2015/109962

Kind Code:

A1

Abstract:

Disclosed is a magnetic separator for improving the grade of a refined ore and reducing slags, comprising a concurrent tank body (6) and a permanently magnetic barrel (3) rotatably provided in the tank body, wherein the rotation direction of the permanently magnetic barrel is opposite to the inlet direction of the ore slurry; a stationary magnetic system (8) is provided in the permanently magnetic barrel; the inlet side of the tank body is connected to a tubular ore-feeding box (16); the included angle of the magnetic system is in the range of 200° - 280°; the magnetic system is of a multi-pole construction; the region of the magnetic system closer to the inlet side of the tank body is a refining region (7) of the magnetic system which is located above the level of the ore slurry in the tank body; at an upstream position in the tank body which corresponds to the refining region of the magnetic system, a plurality of rinsing water pipes (15) are provided on the outside of the permanently magnetic barrel and located above the level of the ore slurry in the tank body; several spraying nozzles (151) facing the permanently magnetic barrel are provided at intervals on the rinsing water pipes; and several stripe-shaped magnetically conductive thin sheets (23) are provided at intervals on an inner wall of the permanently magnetic barrel. The magnetic separator for improving the grade of refined ore and reducing slags can significantly improve the grade of the products and the refined ore thus separated has a high concentration. The device has a compact structure, a large throughput per machine-hour, and a high production efficiency.
